I plan on purchasing a new laptop soon and seeing my brother's 12" PB over Thanksgiving gave me the Mac bug. I have used a PC since college ('90 grad). Initially, I became interested in the iBooks because of price and generally good reviews. Last week, I visited the Apple Store and had my 1st hands on experience with the entire line of Apple notebooks. My impression was that I might prefer a larger screen than the 12" on the base iBook and PB. It also occurred to me that the finish of the iBook cases might be more susceptible to stains, dirt, etc... However, I have read the iBooks are very durable and I like the price and the software package that comes with them. I will mainly be using new computer for email, internet, music, word processing and want one with DVD player and good battery life for occasional travel. Any comments on PB vs. iBook? I am especially interested in: (a) screen size issues (b) scratch/stain resistance/durability of cases, and (c) general performance differences. Also want to know about usefulness of .Mac Thanks for any help.
